I only get the lowest quality texture settings in No Man's Sky regardless of quality settings.

I only get the lowest quality texture settings in No Man's Sky (latest version 1.38) no matter what quality settings I set from Low to Ultra. According to the Steam forum this is a universal problem with AMD cards and the game. Is there a fix coming for this issue? The problem appears to be with the Open GL driver. I also get fairly regular crashes so I have to save the game frequently. I have a Radeon RX 580 8 Gb, 18.2.1 driver, i7-3770 processor and 32 GB RAM. 1920 x 1200 resolution.
